종래의 경우를 제1도 및 제2도를 참조하여 설명하면, 제1도는 종래의 스틸제 범퍼 보강재를 장착한 범퍼 조립체로서, 범퍼 외피(1)와, 상기 범퍼 외피의 내면에 삽입되는 에너지 업소바 폼(2)과, 상기 에너지 업소바 폼을 지지함과 동시에 충격 이너지를 흡수하기 위한 스틸제 보강재(3), 및 상기 보강재(3)의 상부 및 하부에 고정되어 범퍼 외피(1)를 체결시키는 고정 브라켓(4)으로 구성된다.Referring to Figs. 1 and 2, the prior art is a bumper assembly equipped with a conventional steel bumper reinforcement, which is an energy store inserted into the bumper shell 1 and the inner surface of the bumper shell. Fastening the bumper shell (1) is fixed to the bar form (2), the steel reinforcement (3) for supporting the energy absorber foam and absorb the impact energy, and the upper and lower portions of the reinforcement (3) It consists of a fixing bracket (4).
제2도는 종래의 플라스틱제 보강재를 장착한 범퍼 조립체로서, 범퍼 외피(1)와, 상기 범퍼 외피의 내면에 삽입되는 에너지 업소바 폼(2)과, 상기 에너지 업소바 폼을 지지함과 동시에 충격 에너지를 흡수하기 위한 플라스틱제 보강재(5) 및 상기 보강재(5)의 상부 및 하부에 고정되어 범퍼 외피(1)를 체결시키는 브라켓(6)으로 구성된다.2 is a bumper assembly equipped with a conventional plastic reinforcement, which supports and impacts the bumper shell 1, the energy absorber foam 2 inserted into the inner surface of the bumper shell, and the energy absorber foam. It consists of a plastic reinforcement (5) for absorbing energy and a bracket (6) fixed to the upper and lower portions of the reinforcement (5) to fasten the bumper shell (1).
상기 플라스틱제 범퍼 보강재는 스틸제 범퍼 보강재보다 경량이나 고가인 점이 문제로 된다.The problem that the plastic bumper reinforcement is lighter but more expensive than the steel bumper reinforcement.
또한 위와 같은 스틸제 및 플라스틱제 범퍼 보강재는 차량 충돌시, 충격 에너지를 범퍼 외피, 에너지 업소바 폼을 통하여 직접 전달 받는 것이기 때문에, 좀 더 많은 충격 에너지를 흡수할 필요성이 있다.In addition, the steel and plastic bumper reinforcement as described above is required to absorb more impact energy because the impact energy is directly transmitted through the bumper shell and the energy absorber foam during vehicle collision.
따라서, 본 발명은 상술한 종래의 문제점을 극복하기 위한 것으로서, 본 발명의 목적은 스틸제 보강재를 이중으로 설치하고, 이들 보강재 사이에 조인트 러버를 개재시켜, 충격 에너지를 보다 많이 흡수시키는데 있다.Accordingly, the present invention is to overcome the above-mentioned conventional problems, and an object of the present invention is to provide a double reinforcement made of steel, and interpose a joint rubber between these reinforcements to absorb more impact energy.
상기 본 발명의 목적을 달성하기 위한 범퍼 보강재의 일예로서, 범퍼 외피와, 상기 범퍼 외피의 내면에 삽입되는 에너지 업소바 폼과, 상기 에너지 업소바 폼을 지지함과 동시에 충격 에너지를 흡수하기 위한 보강재로 구성된 범퍼 조립체에 있어서, 상기 보강재는 에너지 업소바 폼과 직접 맞닿고, 상부 플랜지 및 하부 플랜지가 구비된 제1보강재와, 상기 제1보강재의 상부 및 하부 플랜지에 대응하는 상부 플랜지 및 하부 플랜지와, 제2에너지 업소바 폼이 장착되는 수직면으로 구성된 제2보강재로 구성되는 것을 특징으로 한다.As an example of a bumper reinforcing material for achieving the object of the present invention, a reinforcing material for absorbing the impact energy while supporting the energy absorber foam, and the energy absorber foam inserted into the inner surface of the bumper shell, and the energy absorber foam In the bumper assembly consisting of: the reinforcement is in direct contact with the energy absorbent foam, the first reinforcement having an upper flange and a lower flange, the upper and lower flanges corresponding to the upper and lower flanges of the first reinforcement and The second reinforcement member is configured of a vertical surface on which the second energy absorbent foam is mounted.
이하, 본 발명의 실시예를 제3도를 참조하여 상세히 설명하기로 한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG.
제3도를 참조하면, 본 발명에 따른 범퍼 보강재를 포함하는 범퍼 조립체는 범퍼 외피(1)와, 상기 범퍼 외피의 내면에 삽입되는 에너지 업소바 폼(2)과, 상기 에너지 업소바 폼을 지지함과 동시에 충격 에너지를 흡수하기 위한 2중 보강재로 구성된다.Referring to FIG. 3, a bumper assembly including a bumper reinforcement according to the present invention supports a bumper shell 1, an energy absorber foam 2 inserted into an inner surface of the bumper shell, and the energy absorber foam. At the same time, it consists of a double reinforcement to absorb impact energy.
상기 2중 보강재는 에너지 업소바 폼(2)과 직접 맞닿고, 상부 플랜지(12) 및 하부 플랜지(13)가 구비된 제1보강재(11)와, 상기 제1보강재(11)의 상부 및 하부 플랜지에 대응하는 상부 플랜지(23) 및 하부 플랜지(24)와, 제2에너지 업소바 폼(22)이 장착되는 수직면(25)으로 구성된 제2보강재(21)로 구성된다.The double reinforcement is in direct contact with the energy absorbent foam 2, and includes a first reinforcement 11 having an upper flange 12 and a lower flange 13, and upper and lower portions of the first reinforcement 11. The second reinforcing material 21 is composed of an upper flange 23 and a lower flange 24 corresponding to the flange, and a vertical surface 25 on which the second energy absorber foam 22 is mounted.
상기 제1보강재(11)와 제2보강재(21)의 상부 및 하부 플랜지 사이에는 조인트 러버(30)가 개재되고, 볼트(31) 및 너트(30)로서 체결된다.A joint rubber 30 is interposed between the upper and lower flanges of the first reinforcing material 11 and the second reinforcing material 21, and is fastened as a bolt 31 and a nut 30.
또한, 상기 제1 및 제2보강재를 스틸로 구성된다.In addition, the first and second reinforcing materials are made of steel.
상기와 같은 구성에 의해 본 발명의 2중 범퍼 보강재는 다음과 같이 작동한다.By the above configuration, the double bumper reinforcement of the present invention operates as follows.
차량의 충돌시, 범퍼 외피에 1차적으로 충격이 전달되고, 2차적으로는 에너지 업소바 폼(2)에 전달되어 충격 에너지를 흡수하게 된다.In the event of a collision of the vehicle, an impact is primarily transmitted to the bumper shell, and secondly, the energy absorber foam 2 is absorbed to absorb the impact energy.
그런 다음, 3차적으로 제1보강재(11)로 전달되어, 충격에너지를 흡수하고, 4차적으로 조인트 러버(30)로 전달되어 충격을 흡수하게 된다.Then, it is transmitted to the first reinforcing material 11 in a third, absorbs the impact energy, and is transmitted to the joint rubber 30 in a fourth order to absorb the impact.
5차적으로 제2에너지 업소바 폼(22) 및 제2보강재(21)로 전달되어 충격에너지를 흡수하고, 차량 프레임에 나머지 충격에너지를 전달하게 된다.The fifth energy absorber foam 22 and the second reinforcing material 21 is delivered to absorb the impact energy, and transmits the remaining impact energy to the vehicle frame.
상술한 바와같이 본 발명에 따른 범퍼 보강재는 스틸제 범퍼 보강재를 이중으로 설치하고, 이들 보강재 사이에 조인트 러버를 개재시켜, 충격 에너지를 보다 많이 흡수시키는 효과가 있다.As described above, the bumper reinforcement according to the present invention has an effect of providing a double bumper reinforcement made of steel and interposing a joint rubber between these reinforcements to absorb more impact energy.
